Maximum leverage for your stop distance: formula and table

CoTrading editorial team 2026-09-23 Updated: 2026-10-25

The maximum leverage for a stop distance is the highest leverage at which liquidation still sits further from entry than your stop: approximately 1 ÷ (stop distance + maintenance margin rate), with both expressed as fractions of entry price. This is a simplified equality threshold, not a safe maximum or a guarantee about which order executes first. It assumes an isolated linear position and omits venue-specific adjustments.

This page is the lookup version, for anyone who has a stop from the chart and wants the ceiling on the leverage setting. The general argument about leverage is in leverage is not risk. By the end you will be able to compute the ceiling for any stop, read it off a table, and decide how much room to leave below it.

Where the formula comes from

For an isolated-margin position on a linear contract, the distance from entry to liquidation is roughly:

distance to liquidation ≈ (1 ÷ leverage) − maintenance margin rate

1 ÷ leverage is the initial margin rate — the fraction of notional you posted. Liquidation happens when losses have eaten that margin down to the maintenance level, not down to zero. The liquidation price calculator runs this for a specific entry, and how liquidation price is calculated walks through it step by step.

For the stop level to lie closer to entry than estimated liquidation in this same-price approximation, the required geometric condition is:

stop distance < (1 ÷ leverage) − MMR

Solve for leverage:

maximum leverage = 1 ÷ (stop distance + MMR)

The stop and the maintenance rate add together, and leverage is the reciprocal of the sum.

The lookup table

Maximum leverage by stop distance, at four maintenance margin rates. The maintenance rates here are illustrative inputs, not any venue’s schedule — real rates are tiered by position size and differ by venue and instrument, so read yours from your venue’s tier table (see what is maintenance margin).

Stop distance	MMR 0.4%	MMR 0.5%	MMR 1%	MMR 2%
0.5%	111.1×	100.0×	66.7×	40.0×
1%	71.4×	66.7×	50.0×	33.3×
1.5%	52.6×	50.0×	40.0×	28.6×
2%	41.7×	40.0×	33.3×	25.0×
3%	29.4×	28.6×	25.0×	20.0×
4%	22.7×	22.2×	20.0×	16.7×
5%	18.5×	18.2×	16.7×	14.3×
7.5%	12.7×	12.5×	11.8×	10.5×
10%	9.6×	9.5×	9.1×	8.3×
15%	6.5×	6.5×	6.2×	5.9×
20%	4.9×	4.9×	4.8×	4.5×

At the listed values, the approximate distances are equal, leaving no modeled separation. A value below the threshold does not guarantee a stop fill, and rounding or the venue’s actual formula can change the ordering.

Two patterns worth noticing:

Stop distance dominates. With a wide stop the maintenance rate barely matters — at 20% every column rounds to about 5×. With a tight stop it matters a lot: at 0.5% the ceiling runs from 111× down to 40× across the columns.
When MMR is small, the ceiling is close to 100 ÷ stop%. A 4% stop caps you at a little under 25×; a 10% stop at a little under 10×. That is a usable mental check before you open any calculator.

The table ignores venue leverage caps, which may sit below some of these figures.

A worked example

Illustrative numbers, not a recommendation: a 10,000 USD account, 100 USD at risk on the trade, a long entry at 60,000 with the stop 2% below at 58,800, and an illustrative maintenance rate of 0.5%.

The position size calculator gives a notional of 100 ÷ 0.02 = 5,000 USD. The ceiling from the table is 40×. Now vary the leverage setting on an isolated position:

Leverage setting	Margin posted	Estimated liquidation distance	Closer level in the approximation
10×	500	9.5%	Stop
20×	250	4.5%	Stop
25×	200	3.5%	Stop
40×	125	2.0%	Tie — liquidation at 58,800
50×	100	1.5%	Liquidation, at 59,100

At 50× the approximation places liquidation at 59,100, closer than the 58,800 stop. A wick that would have touched 59,000 and reversed — a move your plan said was fine — ends the trade.

Account leverage vs the leverage setting

This is the distinction the example exposes, and it is the one people confuse.

Account-level leverage is notional ÷ total balance. Here it is 0.5×, which sounds harmless.

The leverage setting on an isolated position is notional ÷ margin posted to that position. It is what the liquidation formula uses, and it can be 50× while the account-level figure is 0.5×.

Sizing from the stop estimates price loss if the full exit fills there. It does not stop you from posting too little margin behind that position. Under isolated margin, only the posted margin defends the position, so the setting is what has to respect the ceiling. Under cross margin more of the balance stands behind it, which moves liquidation further away — but also puts more of the account in play.

Leave room below the ceiling

The formula is a best case. Four things move real liquidation closer, or move your real exit further:

Fees. Entry and exit fees come out of margin.
Funding. On a perpetual, funding you pay is deducted from margin at each settlement, so liquidation creeps toward entry the longer you hold — see the funding rate calculator.
Stop slippage. A stop-market order fills at the next available price, often beyond the stop, and worst in fast moves — see slippage and market impact.
Tier escalation and reference price. A larger position can fall into a higher maintenance tier, and on venues that trigger liquidation from a mark price rather than the last trade — see what is mark price — the two levels are not measured against the same number.

A buffer b can illustrate extra separation in the simplified model:

leverage ceiling with buffer = 1 ÷ (stop + MMR + b)

At an illustrative 0.5% maintenance rate:

Stop distance	No buffer	Buffer 0.5%	Buffer 1%
1%	66.7×	50.0×	40.0×
2%	40.0×	33.3×	28.6×
3%	28.6×	25.0×	22.2×
5%	18.2×	16.7×	15.4×
10%	9.5×	9.1×	8.7×

No fixed buffer accounts for all four risks or guarantees an exit. In particular, triggering a stop-limit does not guarantee a fill, and mark-price liquidation can precede a stop using another reference price. See the venue explanation and Freqtrade’s stop-order limitations, checked on 2026-10-25. Use the actual contract’s margin rules and order settings.

Where the boundary should sit

The order of decisions matters more than the number:

Place the stop where the idea is invalidated — how to choose a stop-loss level. If it sits inside ordinary movement, widen it first; see volatility and stop distance.
Size the position from the stop and your risk budget.
Look up the ceiling for that stop and your venue’s maintenance rate.
Choose a leverage setting comfortably below it.

If the ceiling feels too low, the fix is more margin behind the position or a smaller position, never a tighter stop. The leverage and stop-loss table runs steps 2–3 with your own inputs, and how leverage changes liquidation distance covers the curve from the other side.

FAQ

What is the maximum leverage for a 2% stop-loss?

Approximately 1 ÷ (0.02 + MMR). With an illustrative 0.5% maintenance margin rate that is 40×, where the approximate distances coincide. It is not a usable safe maximum. A lower setting or added buffer still cannot guarantee that a stop triggers before liquidation or fills at the intended price.

Why does maintenance margin reduce the maximum leverage?

Because liquidation happens when your margin falls to the maintenance level, not to zero. The maintenance rate is margin you cannot lose before the exchange acts, so it shortens the distance to liquidation and adds directly to the stop distance in the denominator of the formula.

Does this apply to cross margin?

The formula assumes isolated margin, where only the margin posted to the position defends it. Under cross margin other balance can absorb losses, which moves liquidation further away, so the isolated figure is the conservative case. The trade-off is that a cross-margin position can draw on more of the account than you intended to put at risk.

Is a lower leverage setting always safer?

For the same quantity, more isolated margin generally moves liquidation further away. Planned price loss remains quantity times stop distance; actual loss still depends on the exit fill, fees and other costs. Moving below the approximate threshold does not guarantee the planned exit.
